I matched my tiny weeny manifold to the carb and cylinder port.

I tried to build the top end today but the new small end bearing is too wide for the piston. Looking at what I took out yesterday that bearing is narrower and accompanied by shims but its still a hair too wide to fit in the piston.
Looks like I have to fettle a little.
